IRRIGATING APPARATUS.

SPECIFICATION forming partlof Letters Patent No. 289,448, dated December 4, 1883'.

Application filed December 30, 1882. (No model.) Patented in France June 25, 1881, No. 143.620; in Italy November 6, 1881, No.

y13,517; in Austria November 7, 1881, No. 10,726, and in Spain November 14, 1881, No. 2,000.

To all whom, it may concern.-

Be lit known that I, JULES ROEINET, of4

Sui ppes, France, have invented a new and useful Improvement in Irrigating Apparatus, (for which I have obtained a patent in France, bearing date June 25, A. D. 1881, No. 143,620; Italy, dated November 6, 1881, No. 13,517 5 Austria, dated November 7, 1881, N o. 10,726; Spain, dated November 14, 1881, No. 2,009,) of which the following is a speciication.

My invention relates to apparatus for irrigating land, and will be rdescribed by means of the accompanying drawings, in which- Figure 1 represents a side elevation and partial section of the driving mechanism, pumps, and air-vessel, while Fig. 2 is a side elevation of an irrigatingtube with supports.

A crank-shaft,D, with iiy-wheel E,ismounted on a beam, U, which supports also, the fulcrum C' for the lever C. rIhe latter is set in motion from the crank-shaft by a connecting rod, B, and serves to drivethe two pumps A A' by means of rods A" A", so that their pistons move in opposite directions. Water is drawn into the pumps through a pipe, F, and delivered by a pipe, G, into an air-vessel, I, from which it flows into the pipes K K' through openings J J There may be one, two, or more such pipes K K', each being provided with a cock or valve, S, and led underground to the point where the water is required. The inlet to the air-vessel is provided with an inlet-valve, h,which, like the valves and pistons of the pumps, may be of any suitable known construction. At any convenient point of the underground pipe K a vertical pipe, L, is led upward,which pipe is bent horizontally at the top P. There may be one or more vertical pipes L branched off from each horizontal pipe K. Over the upper end P fits the end of' the irrigation-tube O, which is supported by several stands, g, and provided with water jets n, or nozzles, at suitable intervals. By turning the horizontal tube O by means of the hand-wheel R, attached to it, the direction of the water-jets may be altered, and for altering the stroke of the pumps A A the upper end of the lever O is provided with a series ofholes, to any of which the pin of the connectingrod may be attached.

What I claim as my invention is.-

1. In irrigating apparatus, the combination of two pumps, A A', driving-lever C C, provided with means for varying the stroke, means for setting the lever in motion from a drivingshaft, suctionpipe F, discharge-pipe G, airvessel I, provided with an inlet-valve, h, and

waterconduit pipes K K', provided with valves or cocks S, substantially as described.v

2. In irrigating apparatus, the combination of a water-conduit pipe, K, with. one or more upright branch pipes, L, each provided with a cock or valve, S', and a horizontal outlet, P, an irrigation-tube, O. supported on stands q, provided with water-jets along the pipe, and with means for turning the tube around the outlet P, substantially as described.

In testimony whereoi'I have signed this specication in the presence of two subscribing witnesses.
